Question

While exercising on cyle ergometer at a given absolute submaximal power output e.g. 100 W. aerobically highly trained individuals will develop:

1. Smaller O2deficit that untrained individuals

2. Larger O2 deficit than untrained individuals

3. Smaller EPOC than untrained individuals

4. Larger EPOC than untrained individuals

5. Larger O2 deficit than EPOC, while untrained will develop larger EPOC than O2 deficit

6. O2 deficit and EOPC, that are always equal to each other

A.6 ONLY

B. 5 ONLY

C. 1 and 3 only

D. 2 and 4 only

E. 1 and 4 only

Explanation / Answer

During first few minutes if aerobic exercises, ATP is produced from the anaerobic systems like creatinine phosphate and glycolysis. This phase is called as oxygen deficit phase. EPOC stands for excess post-exercise oxygen consumption. This is recovery phase which occurs after oxygen deficit phase during exercises. When oxygen deficit is less, EPOC is also less.

Some of the factors which contribute to oxygen deficit and EPOC include replinishment of creatine phosphate, rate of conversion of lactate to pyruvate and resynthesis of glycogen. In aerobically trained individuals, all of these processes occur quickly and therefore they have low oxygen deficit and low EPOC.

Therefore, the answer for this question is option (C), 1 and 3 only.
